Tai Sui (太岁): The Pivot of the Annual Cycle and the Power of the Yearly Sovereign

In Chinese traditional philosophy and belief systems, "Tai Sui" is a core symbol bridging heaven and humanity. "Sui" refers to the measure of time's flow, while "Tai" signifies supreme authority. It serves both as a coordinate in BaZi (八字) fortune analysis, charting the annual energy trajectory, and as a supreme deity in folk religion, governing the fortunes of the year. Understanding the dual nature of Tai Sui is key to interpreting the shifts of yearly cycles.

The Dual Identity of Tai Sui

1. A Marker of Astronomical Calendar

In the BaZi system, "Tai Sui" refers to the "Annual Cycle Earthly Branch" (流年地支). For example, in 2025, the year of Yi-Si (乙巳), the Tai Sui is "Si" (巳). This concept originates from ancient astronomical observations. The ancients noticed that Jupiter (called "Year Star" or Sui Xing) completes a cycle around the heavens approximately every twelve years, using its path to mark years. For computational convenience, they imagined a virtual star moving in the opposite direction at the same speed, naming it "Tai Sui." Today, while its original astronomical meaning has transformed, in BaZi practice, Tai Sui—as the annual Earthly Branch—remains the core measure for observing the flow of heaven and earth's energy in a given year.

2. The Yearly Deity in Folk Religion

In folk religion and Taoist systems, Tai Sui is revered as the "Emperor of the Year" (年中天子), the "Master of the Year, Leader of All Deities." It is said there are sixty Tai Sui star lords, commanded by General Yin Jiao (殷郊) from the Shang Dynasty, who take turns on duty according to the sixty-year cycle of the Heavenly Stems and Earthly Branches. They oversee human merits and faults, governing the year's fortunes. The saying, "When Tai Sui sits overhead, even without disaster, there will be trouble," reflects the awe for this supreme divine authority.

"Offending Tai Sui": The Collision Between Personal Destiny and Annual Energy

"Offending Tai Sui" (犯太岁) is a general term. From a BaZi perspective, it refers to disharmonious interactions—such as Punishment (刑), Clash (冲), Break (破), or Harm (害)—between the Earthly Branch of one's birth year (i.e., the zodiac sign) and the annual Tai Sui Earthly Branch. This indicates a conflict between the individual's energy field and the overall cosmic energy of the year, potentially triggering fluctuations in fortune.

Using 2025 (Year of Yi-Si, Tai Sui Earthly Branch is "Si") as an example:

Dialectics of Fortune and Misfortune from a BaZi Perspective

From a professional BaZi analysis, "offending Tai Sui" is not inherently unlucky. It is more like a signal of energy being "activated" or "triggered." Whether the outcome is auspicious or inauspicious is not solely determined by the zodiac sign. The key lies in whether the triggered Earthly Branch acts as a "Favorable God" (喜神, beneficial energy) or an "Unfavorable God" (忌神, detrimental energy) in the individual's complete BaZi chart.

• Clashing Away the Unfavorable God Turns Auspicious: If a person's zodiac Earthly Branch (e.g., Hai) is an Unfavorable God, then when the annual Tai Sui (e.g., Si) clashes with it, it becomes "the Unfavorable God is restrained." This means the year offers opportunities to break through old difficulties and eliminate chronic problems, which should be seen as auspicious.
• Clashing the Favorable God Brings Misfortune: Conversely, if the clashed Earthly Branch is a Favorable God (e.g., Hai as a Favorable God), it means the foundation is shaken. The year may bring significant upheavals and challenges in career, health, or relationships, indicating misfortune.

Thus, folk customs provide a general "warning" of fortune, while professional BaZi chart analysis offers a "personalized diagnosis," accurately determining whether "offending Tai Sui" is a "crisis" to be wary of or a hidden "turning point" for a specific individual.

Rituals of Honoring the Yearly Sovereign: Worshipping and Sending Off Tai Sui

"Worshipping Tai Sui" (拜太岁) and "Sending Off Tai Sui" (送太岁) are customs rooted in Taoism and folk tradition. Their core is to express reverence to the "Annual Tai Sui Star Lord" and one's "Birth Tai Sui" (the Tai Sui of one's birth year) through specific rituals, seeking protection to safely navigate the year.

Meaning and Origins of the Rituals

• Meaning: Worshipping Tai Sui involves "welcoming" and "sacrificing to" the new annual Tai Sui at the start of the year. The purpose is to report to and pray to the deity in charge of the year's fortunes, seeking to mitigate potential issues from "offending Tai Sui." Sending Off Tai Sui (also called "Thanking Tai Sui") involves thanking the annual Tai Sui for its protection at year's end and respectfully sending it back to its divine position. This "welcoming" and "sending off" form a complete ritual of honoring the deity.
• Origins: The practice of sacrificing to Tai Sui has a long history, with records in the Rites of Zhou (周礼). It was incorporated into state rituals after the Yuan and Ming dynasties. Its philosophical foundation lies in the ancient concept of "heaven and humanity corresponding" (天人相应), believing that through sacrifice, one can harmonize the energy relationship between the individual and the movements of celestial bodies.

Key Steps of the Rituals

• Worshipping Tai Sui: Devotees typically visit Taoist temples to participate in "Shun Xing Bai Tai Sui" (顺星拜太岁) ceremonies. During the ritual, high-ranking Taoist priests chant scriptures, perform ritual steps (步罡踏斗), and present memorials (疏文) to communicate with the deities and pray for blessings. Participants are not limited to those "offending Tai Sui"; anyone wishing for a smooth and safe year can join.
• Sending Off Tai Sui: Held at year's end, the ritual is simpler, focusing on expressing gratitude and respectfully sending off the year's Tai Sui. Typically, the "Tai Sui Talisman" (太岁符) obtained at the beginning of the year is burned during this time to signify farewell.

Tai Sui Talisman: A Protective Token

The Tai Sui Talisman is a special Taoist talisman used to pray for the protection of the Tai Sui deity. A proper Tai Sui Talisman should be written by a Taoist priest on yellow paper with cinnabar at an auspicious time, stamped with a ritual seal, and consecrated through a ceremony. It is considered a token carrying the deity's power and can be worn on the person or placed in the home.

Timing: When to Welcome and Send Off?

• Worshipping Tai Sui (Welcoming the New Year):
  • Earliest Opportunity: Winter Solstice (冬至). The ancients believed that at the Winter Solstice, "one yang is born" (一阳生), marking the beginning of the new year's energy. The influence of the old Tai Sui begins to wane, making it possible to start worshipping the new year's Tai Sui.
  • Best Period: From the twelfth lunar month to the fifteenth day of the first lunar month. This period, bridging the old and new years, is considered the time for deities to "report and change shifts" in Taoist belief, making it ideal for "sending off the old and welcoming the new" rituals, with the strongest spiritual resonance.
• Sending Off Tai Sui (Thanking the Old Year):
  • Must be completed before the ritual of worshipping the new year's Tai Sui.
  • Best Period: Around the Little New Year (Xiao Nian, 小年) in the twelfth lunar month, and no later than the Start of Spring (立春) of the current year. Sending off the old year's Tai Sui at this time, thanking it for its year-long protection, ensures a complete and proper conclusion.

Classical Text

From San Ming Tong Hui (三命通会)

The Tai Sui is the master of the year and the leader of all deities. There are two types: the birth year in the Four Pillars is called the "Birth Tai Sui" (当生太岁), and the annual rotating branch is called the "Traveling Tai Sui" (游行太岁). The Birth Tai Sui governs one's entire life, as discussed earlier; the Traveling Tai Sui moves through the twelve palaces annually, determining the year's fortune and misfortune. The Tai Sui is like a ruler, and the Luck Cycle (大运) is like a minister. If the ruler and minister are harmonious, the year is auspicious; if they clash and conflict, the year is inauspicious. The classics say: If the Tai Sui harms the Day Master, the disaster is light; if the Day Master offends the Tai Sui, the calamity is heavy. This can be further explained: When the Tai Sui harms the Day Master, such as a Geng year overcoming a Jia day, forming a Warlord (偏官), it is like a ruler governing a minister or a father disciplining a son. Even if there are disasters, they are not severe. Why? Because the superior governing the inferior is natural, and the relationship is not completely severed. When the Day Master offends the Tai Sui, such as a Jia day overcoming a Wu year, forming a Venturer (偏财), it is like a minister offending the ruler or a son defying the father, which is highly unfavorable. Why? Because the inferior challenging the superior is rebellious, and misfortune is unavoidable. However, if the Five Elements provide salvation or the Four Pillars show affection, it can be different. For example, if a Jia day overcomes a Wu year, but the Four Pillars already have Geng or Shen metal, or the Luck Cycle also has metal to subdue the Jia wood, preventing it from overcoming the Wu earth, this is salvation. Or if the Luck Cycle or Four Pillars have Gui water to combine with Wu earth (Wu-Gui combination), this is affection. The classics say: If the Ren water Day Master encounters Wu earth as a Warlord, and Gui water (Ren's sister) combines with Wu earth, it can turn misfortune into good fortune.

There are also concepts of "True Tai Sui" (真太岁) and "Conquering Tai Sui" (征太岁). The classics say: When the birth hour meets the annual cycle, it is called "True Tai Sui." For example, a person born in a Jia Zi year encountering another Jia Zi year is called "True Tai Sui," also known as "Zhuan Zhi Sha" (转趾煞). In this case, the Luck Cycle and Day Master must be harmonious with the Tai Sui for the year to be auspicious; if there are Punishments, Clashes, Breaks, or Harms, and mutual conflict with the Tai Sui, it is inauspicious. Another example: A Gui Si day encountering a Ding Hai year; the day stem-branch clashing and overcoming the Tai Sui (Gui overcomes Ding, Si-Hai Clash) is called "Conquering" (征). If the Luck Cycle stem-branch harms or clashes the Tai Sui, it is also called "Conquering." If the Tai Sui stem-branch clashes the day stem-branch, it is also called "Conquering." Such years are often inauspicious, with unavoidable disasters. Another example: A Jia Zi year coinciding with a Jia Zi Luck Cycle is called "Year and Luck Coinciding" (岁运并临). Only if it coincides with a Blade (羊刃) or Warlord (七杀) is it inauspicious; if it coincides with Wealth, Executive, or Seal, it is auspicious. Another example: A Jia Zi day encountering a Jia Zi Tai Sui is called "Day and Year Coinciding" (日年相并). If a noble person encounters it, it is called "Ruler and Minister Meeting," favorable for audiences with the emperor. If a local scholar encounters it, it indicates promotion. However, this requires harmony with the Tai Sui and the day branch (帝座) to be extraordinary. If an ordinary person encounters it, it is most unfavorable. If the birth hour harmonizes with the Tai Sui, the disaster is lighter. Hence, the classics say: "When Tai Sui stands overhead, all deities dare not contend. If no official trouble disturbs, a major funeral is certain." This is the case! If combined with various inauspicious stars like Gou Chen, Wang Shen, Xian Chi, Gu Chen, Zhai Mu, Bing Fu, Si Fu, Guan Fu, Sang Men, Diao Ke, Bai Hu, Yang Ren, Bao Bai, Tian E, etc., disasters multiply, and death may occur.

For example, if a Jia day encounters a Wu year Tai Sui (Day Offends Tai Sui), and Jia wood is born in Yin, Mao, Hai, or Wei months (making it strong), and the year, month, day, and hour pillars have many Jia or Yi wood to overcome Wu earth, while the Wu year pillar lacks Geng, Xin, Si, You, Chou metal to control the wood, or Bing, Ding fire to consume the wood, it is very inauspicious. Example: A chart with Wu Chen, Wu Wu, Wu Xu, Jia Yin (Blade turned backward), encountering a Ren Shen year in the fourth month, developed a malignant sore on the neck, and nearly died from a severed head. Another chart: Yi Chou, Yi Hai, Ren Shen, Yi Si, running Xin Wei Luck Cycle, encountering a Bing Yin year. The day stem Ren water overcomes the Tai Sui Bing fire; the day branch Shen's Geng metal overcomes the Tai Sui Yin's Jia wood; also forming Yin-Si Punishment, Si-Shen Punishment, Shen-Yin Punishment; the Xin Wei Luck Cycle combines with the Tai Sui Bing Yin to form a wood Maverick (伤官) pattern, all inauspicious. That year, Bing Wu, fire was strong and conflicted, leading to an unnatural death.

Generally, when the Day Master offends the Tai Sui, it is heavier for the five Yang stems (Jia, Bing, Wu, Geng, Ren) and lighter for the five Yin stems (Yi, Ding, Ji, Xin, Gui). If the Day Master is a Heavenly Virtue or Monthly Virtue Noble, or if the Tai Sui is the Useful God (用神), there is no disaster and instead gains. If the original chart already has a Heavenly Clash and Earthly Strike, and the annual cycle encounters it again, there is no major harm. If the Tai Sui overcomes the birth hour stem-branch, or the hour overcomes the Tai Sui, it also indicates disaster, but it is judged based on the child position.

Modern Interpretation: Tai Sui is the master of the year and leader of all deities. There are two types: the birth year pillar (Birth Tai Sui) governs one's life, while the annual Earthly Branch (Traveling Tai Sui) determines the year's fortune. The Tai Sui is like a ruler, and the Luck Cycle is like a minister. Harmony brings good fortune; conflict brings misfortune. If the Tai Sui harms the Day Master, the disaster is lighter; if the Day Master offends the Tai Sui, the calamity is heavier. However, if the Five Elements provide salvation or the Four Pillars show affection, it can turn misfortune into good fortune. Concepts like True Tai Sui and Conquering Tai Sui describe specific interactions that can be auspicious or inauspicious depending on the chart. The severity of the Day Master offending the Tai Sui depends on the stem's yin-yang nature and the presence of nobles or the Useful God.
